The AirTAC Airtac SC40 Standard Cylinder SC40X145S is a genuine double-acting standard air cylinder with a Ø40mm bore and 145mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X145S is a double-acting pneumatic cylinder with a 40 mm bore and 145 mm stroke, pre-fitted with a magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it supplies 628 N extending and 528 N retracting, rising to 1130 N push at 0.9 MPa.
This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the 145 mm travel, and the tie-rod construction keeps the body length A to just 142 mm.

The 145 mm stroke and magnetic piston sensing suit diverting packages on belt conveyors, where the sensor confirms the gate is fully retracted before the next cycle.
With 628 N of push force at standard line pressure, this cylinder handles light assembly presses, glue clamps, and holding fixtures for wood or plastic parts.
The clean, oil-free air operation and compact 142 mm body length make it a good fit for automated test-stand actuators that need position feedback via the magnet.
For a step up in force, the 50 mm bore SC50 series provides 982 N push at 0.5 MPa; for a lighter, more compact option the 32 mm bore delivers 402 N. The built-in magnet (suffix -S) allows barrel-mounted reed or solid-state sensors to confirm end-of-stroke position without brackets on the rod.
When replacing this cylinder, match five points: 40 mm bore, 145 mm stroke, PT1/4 port thread, the basic (no bracket) mounting, and the magnet option. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel tie-rod slots to detect piston position.
